Description:

This application claims benefit of U.S. Provisional Application No. 60/617,682, filed May 13, 2004, the contents of which are incorporated herein by reference. This application also claims benefit of priority under 35 U.S.C. § 119 to French Patent Application No. 04 50927, filed May 13, 2004, the contents of which are also incorporated by reference.

Disclosed herein is a cosmetic makeup or skincare composition in powder form comprising at least one elastomeric organopolysiloxane powder combined with other powders. Further disclosed herein is a process for making up and/or caring for human skin comprising applying at least one such cosmetic composition to the skin.

In one embodiment, the cosmetic composition disclosed herein is a makeup composition. The makeup composition may be, for example, in the form of a skin makeup composition, such as a foundation, an eyeshadow, a makeup rouge, a concealer product, a face and body powder, or a body makeup product. In one embodiment, the makeup composition disclosed herein may be a foundation composition.

In another embodiment, the cosmetic composition disclosed herein is a skincare composition. The skincare composition may be in the form of a facial care product, a body care product, or a deodorant powder.

Skin makeup compositions may commonly be used to give an attractive color to the skin, such as the face, but also to mask skin imperfections, such as redness, marks and wrinkles.

Certain makeup compositions may be in the form of loose powders or compacted powders. These compositions generally comprise a high content of powders, for example, at least 80% by weight of powders, relative to the total weight of the composition. Depending on the type of powders used, the cosmetic properties of the makeup product may be very variable. However, certain powders, for example, calcium carbonate, magnesium carbonate, magnesium stearate or titanium dioxide, may give a dry, coarse feel and may be detrimental in terms of obtaining softness properties when the cosmetic powder is taken up on the finger or spread onto the skin. Furthermore, with these pulverulent materials, the deposit of the cosmetic powder on the skin may be opaque and covering, and therefore may not make it possible to obtain a transparent and masking makeup result or a makeup result that fades out the imperfections of the skin relief, for instance microreliefs, wrinkles and fine lines. The powder deposited on the skin may be very visible and may have a pronounced powdery appearance dissimilar to the natural grain of the skin: the makeup result may not be natural.

Thus, it would be desirable to provide a makeup or skincare composition in powder form that has at least one good property in terms of softness when applied to the skin and that allows a deposit, for example, a makeup result, to be obtained that is transparent and that masks the imperfections of the skin relief, for instance microreliefs, wrinkles and fine lines, while maintaining a low covering effect.

It would also be desirable to provide a cosmetic composition in powder form which allows a deposit to be obtained on the skin that is natural and not very powdery, allowing the natural grain of the skin to show through.

The present inventors have discovered that such a composition can be obtained by combining at least one elastomeric organopolysiloxane powder with other particular powders.

In one embodiment, the present disclosure relates to a cosmetic composition comprising at least one elastomeric organopolysiloxane powder, which may be cross-linked; at least one spherical filler; and at least one N-acylated amino acid powder, wherein the composition is in powder form.

In another embodiment, disclosed herein is a cosmetic composition comprising at least one elastomeric organopolysiloxane powder, which may be cross-linked, and at least one spherical filler, wherein the composition is free of compounds-chosen from calcium carbonate, magnesium carbonate, magnesium hydrocarbonate, chalks, titanium dioxide, and metal soaps derived from organic carboxylic acids comprising from 8 to 22 carbon atoms, such as 12 to 18 carbon atoms, for example, zinc stearate, magnesium stearate, lithium stearate, zinc laurate, and magnesium myristate, and wherein the composition is in powder form.

In a further embodiment, disclosed herein is a cosmetic composition comprising at least two elastomeric organopolysiloxane powders and at least one N-acylated amino acid powder, wherein the composition is in powder form.

In yet another embodiment, disclosed herein is a cosmetic composition comprising at least one elastomeric organopolysiloxane powder; at least one polymethyl methacrylate powder; and at least one N-acylated amino acid powder, wherein the composition is in powder form.

Additionally disclosed herein is a cosmetic composition comprising at least one elastomeric organopolysiloxane powder and at least one polyurethane powder, wherein the composition is in powder form.

A further embodiment disclosed herein is a cosmetic composition comprising at least one elastomeric organopolysiloxane powder and at least one acrylic polymer powder other than a polymethyl methacrylate powder, wherein the composition is in powder form.

Disclosed herein is a non-therapeutic cosmetic process for making up and/or treating the skin, comprising applying to the skin a composition disclosed herein.

Further disclosed herein is the use of a composition as disclosed herein for obtaining a deposit, for example, a makeup result, on the skin that is transparent and/or that masks the imperfections of the skin relief and/or that is natural and/or that allows the grain of the skin to show through.

The composition disclosed herein comprises at least one elastomeric organopolysiloxane powder, which may, for example, be spherical.

The at least one elastomeric organopolysiloxane may, for example, be crosslinked and may be obtained via a crosslinking addition reaction of diorganopolysiloxane comprising at least one hydrogen linked to silicon and of diorganopolysiloxane comprising ethylenically unsaturated groups linked to silicon, in the presence, for example, of a platinum catalyst; or via a dehydrogenation crosslinking condensation reaction between a diorganopolysiloxane comprising hydroxyl end groups and a diorganopolysiloxane comprising at least one hydrogen linked to silicon, in the presence of, for example, an organotin; or via a crosslinking condensation reaction of a diorganopolysiloxane comprising hydroxyl end groups and of a hydrolysable organopolysilane; or via thermal crosslinking of organopolysiloxane, for example, in the presence of an organoperoxide catalyst; or via crosslinking of organopolysiloxane by high-energy radiation such as gamma rays, ultraviolet rays or an electron beam.

In one embodiment, the at least one elastomeric organopolysiloxane powder is crosslinked and is obtained via a crosslinking addition reaction (A2) of diorganopolysiloxane comprising at least two hydrogens, each linked to a silicon, and (B2) of diorganopolysiloxane comprising at least two ethylenically unsaturated groups linked to silicon, for example, in the presence (C2) of a platinum catalyst, for instance as described in Patent Application No. EP-A-295 886.

For example, the organopolysiloxane may be obtained via a reaction of dimethylpolysiloxane comprising dimethylvinylsiloxy end groups and of methylhydrogenopolysiloxane comprising trimethylsiloxy end groups, in the presence of a platinum catalyst.

Compound (A2) is the base reagent for the formation of elastomeric organopolysiloxane and the crosslinking takes place via an addition reaction of compound (A2) with compound (B2) in the presence of the catalyst (C2).

Compound (A2) may, for example, be a diorganopolysiloxane comprising at least two lower alkenyl groups (for example C2-C4); the lower alkenyl group may be chosen from vinyl, allyl and propenyl groups. These lower alkenyl groups may be located in any position of the organopolysiloxane molecule, but in one embodiment are located at the ends of the organopolysiloxane molecule. The organopolysiloxane (A2) may have a branched-chain, linear-chain, cyclic or network structure; in one embodiment, the linear-chain structure may be used. Compound (A2) may have a viscosity ranging from the liquid state to the gum state. For example, compound (A2) may have a viscosity of at least 100 centistokes at 25° C.

The organopolysiloxanes (A2) may be chosen from methylvinylsiloxanes, methylvinylsiloxane-dimethylsiloxane copolymers, dimethylpolysiloxanes comprising dimethylvinylsiloxy end groups, dimethylsiloxane-methylphenylsiloxane copolymers comprising dimethylvinylsiloxy end groups, dimethylsiloxane-diphenylsiloxane-methylvinylsiloxane copolymers comprising dimethylvinylsiloxy end groups, dimethyl-siloxane-methylvinylsiloxane copolymers comprising trimethylsiloxy end groups, dimethylsiloxane-methylphenylsiloxane-methylvinylsiloxane copolymers comprising trimethylsiloxy end groups, methyl(3,3,3-trifluoropropyl)polysiloxane comprising dimethylvinylsiloxy end groups, and dimethylsiloxane-methyl(3,3,3-trifluoropropyl)siloxane copolymers comprising dimethylvinylsiloxy end groups.

Compound (B2) may, for example, be an organopolysiloxane comprising at least two hydrogens linked to silicon in each molecule and is thus the crosslinking agent for the compound (A2).

In one embodiment, the sum of the number of ethylenic groups per molecule of compound (A2) and the number of hydrogen atoms linked to silicon per molecule of compound (B2) is at least 4.

Compound (B2) may be of any molecular structure. In one embodiment, compounds (B2) is of linear-chain or branched-chain structure or cyclic structure.

Compound (B2) may have a viscosity at 25° C. ranging from 1 to 50 000 centistokes, for example, in order to have good miscibility with compound (A).

In one embodiment, compound (B2) may be added in an amount such that the molecular ratio between the total amount of hydrogen atoms linked to silicon in compound (B2) and the total amount of all the ethylenically unsaturated groups in compound (A2) is within the range from 1:1 to 20:1.

Compound (B2) may be chosen from methylhydrogenopolysiloxanes comprising trimethylsiloxy end groups, dimethylsiloxane-methylhydrogenosiloxane copolymers comprising trimethylsiloxy end groups, and cyclic dimethylsiloxane-methylhydrogenosiloxane copolymers.

Compound (C2) is the crosslinking reaction catalyst, and may, for example, be chosen from chloroplatinic acid, chloroplatinic acid-olefin complexes, chloroplatinic acid-alkenylsiloxane complexes, chloroplatinic acid-diketone complexes, platinum black, and platinum on a support.

The catalyst (C2) may, for example, be added in an amount ranging from 0.1 to 1000 parts by weight and, further, for example, from 1 to 100 parts by weight, as clean platinum metal, per 1000 parts by weight of the total amount of compounds (A2) and (B2).

Other organic groups may be linked to silicon in the organopolysiloxanes (A2) and (B2) described previously, for example, alkyl groups, such as methyl, ethyl, propyl, butyl or octyl; substituted alkyl groups, such as 2-phenylethyl, 2-phenylpropyl or 3,3,3-tri-fluoropropyl; aryl groups, such as phenyl, tolyl or xylyl; substituted aryl groups, such as phenylethyl; and substituted monovalent hydrocarbon-based groups, such as an epoxy group, a carboxylate ester group or a mercapto group.

In some embodiments, the at least one elastomeric organopolysiloxane powder may, for example, be chosen from non-emulsifying elastomers. As used herein, the term “non-emulsifying” means organopolysiloxane elastomers not comprising a hydrophilic chain, such as polyoxyalkylene or polyglycerolated units.

The at least one spherical filler may, for example, be non-elastomeric. In some embodiments, the at least one spherical filler is not film-forming, i.e. it does not form a continuous film when deposited onto a support such as the skin.

The at least one spherical filler may be chosen, for example, from: acrylic powders, for example, polymethyl methacrylate powders, acrylic powders other than polymethyl methacrylate powders, polyurethane powders, and the powders described below.

The composition disclosed herein may comprise the at least one spherical filler in an amount ranging from 10% to 40% by weight, for example, ranging from 15% to 35% by weight, further, for example, ranging from 15% to 30% by weight and, even further, for example, ranging from 15% to 25% by weight, relative to the total weight of the composition.

According to one embodiment, the composition may comprise at least one powder, for example, a spherical powder, of polymethyl methacrylate.

The at least one polymethyl methacrylate powder may be in the form of hollow or solid white spherical particles generally with a number-average size of micrometer order, for example, ranging from 3 to 15 microns and, further, for example, ranging from 3 to 10 microns. As used herein, the expression “number-average size” means the size given by the statistical particle size distribution to half of the population, referred to as D50.

It is also possible to characterize the polymethyl methacrylate particles by their density, which can vary, for example, as a function of the size of the spherical cavity of the particles.

In accordance with the embodiments disclosed herein, this density is assessed according to the following protocol, referred to as the packed density:

    • m=40 g of powder is poured into a measuring cylinder; the measuring cylinder is then placed on a Stav 2003 machine from Stampf Volumeter; the measuring cylinder is then subjected to 1500 packing motions; the final volume Vf of packed powder is then measured directly on the measuring cylinder. The packed density is determined by the ratio m/Vf, in this instance 40/Vf (Vf being expressed in cm3 and m in g).

For example, the density of the at least one polymethyl methacrylate powder that may be used in the embodiments disclosed herein may range, for example, from 0.3 to 1.5, further, for example, from 0.5 to 1.5 and, even further, for example, from 1 to 1.5.

For example, the particles may be made of any expanded acrylonitrile polymer or copolymer that is non-toxic and a non-irritant to the skin.

For example, the mass per unit volume of the particles is chosen in the range from 15 kg/m3 to 200 kg/m3, for example, from 40 kg/m3 to 120 kg/m3 and even further, for example, from 60 kg/m3 to 80 kg/m3. To obtain this low mass per unit volume, expanded polymer or copolymer particles, for example, based on acrylonitrile and on an acrylic or styrene monomer and/or on vinylidene chloride may, for example, be used.

It is possible to use, for example, a copolymer comprising: from 0% to 60% of units derived from vinylidene chloride, from 20% to 90% of units derived from acrylonitrile and from 0% to 50% of units derived from an acrylic or styrene monomer, wherein the sum of the percentages (by weight) is equal to 100.
